CHAR_BIT是char中的位数。它以C ++语言在“ limits.h”头文件中声明。每字节8位。
这是C ++语言中CHAR_BIT的示例,
#include <bits/stdc++.h> using namespace std; int main() { int x = 28; int a = CHAR_BIT*sizeof(x); stack<bool> s; cout << "The number is : " << x << endl; for (int i=1; i<=a; i++) { s.push(x%2); x = x/2; } cout << "The number of bits in a byte : " << CHAR_BIT << endl; for (int i=1; i<=a; i++) { cout << s.top(); s.pop(); if (i % CHAR_BIT == 0) cout << " "; } return 0; }
输出结果
The number is : 28 The number of bits in a byte : 8 00000000 00000000 00000000 00011100
